Question

How much ammonium nitrate (NH4NO3) is needed to prepare a 400.0 g solution with a concentration of 7.50% of NH4NO3?

science chemistry

Answer 1

Answer #1

percentage of NH4NO3 = ((mass of NH4NO3)/(mass of solution))*100

mass of solution = 400.0 g

mass of NH4NO3 = ?

7.50 = ((mass of NH4NO3)/(400))*100

mass of NH4NO3 = (7.50*400)/100

= 30 g
